We usually try to do IHs on Saturdays and Sundays as that is when traffic peaks and we can get 2 and sometimes even 3 games going simultaneously.

A year ago I was spamming my ally chat after a 25-0 Cyprus and 5 lost towers at 20 min:
"BUY BKBBBBB - PLEAAAASE BUY BKBBBBB"
everybody ignored me haha, RIP
how is it going? still doing IHes?
if so I gladly come along for a few!

Yeah I see the angle for the item but in reality the 100% resist for a full 8 seconds just completely nullifies a lot of heroes' and items in the game. It also acts like a parallax which I'm not sure if it's intended but basically any spell stun ability will do nothing, no stun. In terms of baiting for a team fight, 8 seconds is long enough to even if it is baited engage with because again, you have a full 8 seconds of spell immunity and nothing can stun you. I find it most annoying in the late game as a lot of heroes won't have the item before 35+ minutes into the game, so if I'm tass and I push tab, I see no Tetra, I continue to build spell dmg- 20 or so minutes later a wild tetra appears and I now do basically 0 dmg to that hero. I strongly am for a decay or at the very least some sort of trade off- like taking 100% extra physical dmg after the duration ends.

Yes, it would be helpful but it's only me at this time and I honestly don't have that kind of time. What time I do have I dedicate to the game itself.
If members of the community want to rise up and help update this and the wiki database I will gladly try to facilitate everything they need. Until then the best and most updated source of information on heroes can be found in the game and in patchnotes.

The idea is that the item has its place, purpose and drawbacks. It’s only spell immunity, which can be countered by other types of damage at best or baiting the active out prematurely at worst, leaving the item in cooldown for the rest of the team fight.
Team comps should be balanced so that you have ranged and melee, different types of damage coming from different roles. If you are all spell damage that’s on you not Tetra for example. In AoS, you have the advantage of seeing what items the enemy is purchasing in real time with a click of a button, this should not be underestimated as you can infer what the enemy plan is and counter it before it reaches fruition.
On the other end, Tetra is finally being recognized by players after being in the game for a long time. If it gets out of hand, we can revisit its price, active duration, and/or silence penalty.
